Black-billed Magpie (American Magpie)
Primary flight feather (Remiges), likely an outer primary (P7-P9)

Black-billed Magpie (American Magpie)

Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Passeriformes, Family: Corvidae, Genus: Pica, Species: Pica hudsonia

Family: Corvidae (Crows, Jays, and Magpies)

Shape
Highly asymmetrical with a narrow, stiff leading edge and a broader trailing vane; the tip is slightly rounded to tapered, characteristic of high-maneuverability flight.
Size
Approximately 12-15 cm (4.7-6 inches) in length. This is consistent with the outer primary feathers of an adult Black-billed Magpie.
Rarity
Common; they are abundant and highly conspicuous residents within their geographic range.

Description

This feather belongs to the Black-billed Magpie, a large, charismatic songbird. The bird is approximately 18-24 inches long with an exceptionally long tail. In flight, these white primary 'windows' flash brilliantly against the bird's otherwise dark, iridescent plumage. They are known for their bold personalities, complex social structures, and striking contrast of black, white, and teal-blue.

Colour & Pattern

Striking bicolored pattern: the basal two-thirds of the inner vane is pure white, while the distal third and the entire outer vane are deep iridescent black with blue-green highlights. The white 'window' is a diagnostic field mark visible in flight.

Barb Structure

Pennaceous; tightly interlocked barbs with well-developed hooklets (barbicels) providing a stiff, aerodynamic surface. The distal end shows higher melanin density for structural reinforcement.

Texture & Surface

The surface is glossy and smooth. The dark sections exhibit a structural iridescence, appearing oily or metallic in direct light. The vane is rigid yet flexible enough for powerful flight.

Key Features

Distinguished by the sharp, clean division between the white base and the iridescent black tip on a highly asymmetrical primary feather.

Habitat

Open woodlands, riparian thickets, meadows, and sagebrush plains. Highly adaptable to human-dominated landscapes like farms and suburban edges with scattered trees.

Geographic Range

Western North America, ranging from coastal Alaska and western Canada down through the Rocky Mountains and Great Plains to the Southwestern United States.

Ecological Role

Omnivorous scavengers and predators. They play a vital role in cleaning up carrion and controlling insect populations. They also act as 'sentinels,' alerting other animals to the presence of predators.

Similar Species

Eurasian Magpie (Pica pica) feathers are nearly identical but found in a different geographic range. Yellow-billed Magpie (Pica nuttalli) feathers are also similar but restricted to California.

Interesting Facts

Magpies are among the most intelligent animals on Earth; they are one of the few non-mammal species known to pass the mirror test (self-recognition). They are also known to hold 'funerals' for deceased flock members.

Condition Notes

Good to Excellent. The vane is mostly intact with minor 'zipping' issues at the tip. No significant sun-bleaching or parasite damage is visible, suggesting a relatively recent molt.
